Установите Perl в PostgreSQL, указанный модуль не найден.
Здесь я предлагаю несколько шагов, которые помогут вам установить Perl в Windows PostgreSQL
*
1) УстановитеActivePerl, чтобы ваши окна поддерживали Perl-скрипт. *
2) Установите папку bin Perl в переменную среды Windows
3) Перезапустите PostgreSQL
4) Выполните команду Createlang
C:\>createlang -U postgres plperl DB_NAME
Если вы столкнулись с ошибкой“The specified module could not be found”, просмотрите мою историю ниже.

C:\>createlang -U postgres plperl postgres createlang: language installation failed: ERROR: could not load library "C:/Program Files/PostgreSQ L/8.2/lib/plperl.dll": The specified module could not be found.
+ hmm… It’s seem i’m missing plperl.dll file in my PostgreSQL library folder, however i check plperl.dll indeed exists in my PostgreSQL lib folder. I started to wonder what went wrong with this dll file? I downloaded a software call http://www.dependencywalker.com/[“Dependency walker”], it is a small program to check what are the dependency of a dll file. After check with Dependency walker, i find out plperl.dll is depend on a dll file call perl58.dll. As i know , Perl58.dll is a dll file in Perl version 5.8. haha.. ya i forgot to install Perl script in my windows, go here http://www.activestate.com/downloads/index.mhtml to install Active Perl on window. After install please remember to set Perl bin folder to windows environment variable. Try it again, + **
C:\>createlang -U postgres plperl postgres createlang: language installation failed: ERROR: could not load library "C:/Program Files/PostgreSQ L/8.2/lib/plperl.dll": The specified module could not be found.
+ ….WTF… i check with “Dependency walker”, everything is ok. All dll files are loaded. It drive me insane, and shut down PostgreSQL immediately. After few hours, i started PostgreSQL again, and issue command
C:\>createlang -U postgres plperl DB_NAME
Ух, plperl установлен в моем PostgreSQL успешно. …………restart…..this is windows.
